* #800 & #901 CARRY CASE

DOPPLERS: The determining factor in choosing a probe type and operating frequency is the depth of the vessel.  For best results from shallow vessels we recommend a nominal 8 or 9 MHz probe and most people find it adequate for all their vascular needs.

For dual frequency directional Dopplers, we recommend nominal 4 and nominal 8 or 9 MHz.  The 4 MHz probe is bigger (½ inch diameter) but there is considerable improvement in the detection of deeper arteries and veins, especially on obese or swollen limbs.

PROBES: When you order a Doppler it comes with a probe of your choice compatible with the instrument. We recommend that you have two probes for general usage Dopplers like the Model 811-B, Model 812, etc.  Since probes fail more often than instruments, a spare probe lets you know whether it was the instrument or the probe that failed.  It’s a good investment for Dopplers you depend on.
However, we do not recommend spares for probes that are 4 MHz or lower in frequency (such as chest probes, obstetrical probes, etc.).  These probes are rugged and for best performance the instrument needs to be factory-tuned to a specific probe.

FLAT PROBES: Use flat probes for routine blood-pressure measurements on the arms.  We have infant and adult sizes.  You can use the probes interchangeably.  The infant size is made in nominal 8 and 9 MHz frequencies.  We make a flat 5 MHz probe but generally do not recommend it.

AVIAN PROBE: Veterinary use, call for details

NOTE: The probe frequency must match the frequency of the instrument. You cannot use a 4 or 5 MHz probe on an instrument tuned to 8 or 9 MHz. You can mix the probe style, but not the frequency.

SURGERY: The Model 811 series provides adequate service in surgery because you normally only want to judge blood flow quality by ear.  If you want blood flow indicated on a meter for later comparison, we recommend our Model 810-A or 810-B.  If you need a directional Doppler, the Model 806-CB is the next step up.  If you also need a recording, the Model 1050-C will do it.  Generally, in surgery, use a nominal 8 or 9 MHz probe. Microvascular probe also available, call for details.

CARRY CASES: Our workhorse Doppler in pediatrics, surgery, ICU, and the emergency room is the Model 811-B and its variations.  Models 811-B, 811-BL, 811-BTS, 801-B, 812, 915-BL and 614-B come standard in a rugged aluminum box.  These instruments are also available in an attractive aluminum case with convenient carry handle, removable lid and room for accessories.

#800 case (9.25” L x 7.25” W x 4.00” D) large enough to hold a bottle of gel, probe and battery charger -- available in blue only.

#900/901 case (11.30” L x 8.40” W x 5.00” D) has the same features as above, but with additional space for a manometer and a few cuffs -- available in off white only.

If you own an older Doppler in a plastic case you can order a metal case for it. When you order a metal case, be sure to specify what model it is for.

These instruments never really wear out.  We occasionally get instruments in for service that were made 30 years ago and they work fine.  The actual sensitivity of Doppler has not changed much in that time, and ours has always been the best.

What has changed is batteries, cases, whether or not there is a speaker or recorder or meters on the front panel.  The basic doppler is about the same as it was 30 years ago.  No one but Parks has been making dopplers nearly that long.  We were #2 to make clinical doppler ultrasound.  Smith-Kline Instruments was first, with the "Doptone".  Imex, Medasonics, Sonicaid, Life Sciences and a host of others both here and abroad started many years later.  Many companies have dropped by the wayside.
